GÜNTHER’s portfolio includes a variety of valve gate nozzles and needle actuation options. This enables perfect application-specific adaptation to the mould concept, both technically and financially. Both the smallest and large shot volumes and gate diameters from 0.8 to 4.0 mm can be implemented with valve gate technology. The innovative design of the needle guide and the optimised shut-off needle enable low-wear operation. During the shut-off movement, the needle is first led over a cone up
to the cylindrical pre-centring device for precise immersion into the cylindrical gate point. The needle guide is supported floating in the melt channel. In case of wear, the needle guide can be changed with minimal effort . Special openings in the mould clamping plate enable individual adjustment of the immersion depth of the shut-off needle from the outside. Depending on the application, highly filled plastics can be processed.

Valve gate nozzle type 8NEST
Needle guide LAZMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without subsequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring. Needle guide type LAZ has a tapered shape with a smaller contact surface which creates a smaller impression. This version is suitable for items with a minimal wall thickness and part geometries not permitting a larger impression.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of the
mould inserts required- Minimal shear stress
Needle guide KAThis is used when a second marking on the part is not permissible.
When selecting the material to be used, the needle hardness of 64 ±2 HRC is to be taken into account!

NEEDLE GUIDE VERSIONS
Needle guide version Antechamber version LA
Needle guide version Antechamber version LA
with titanium ring
Valve gate nozzle type 4NHFNeedle guide versions LA, LA with titanium ring, LAZ and KA
Needle guide LAMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without sub-sequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of
the mould inserts required- Minimal shear stress
Needle guide LASpecial version with titanium ring
Thermal insulation of the needle guide using a titanium ring expands the area of use of the valve gate nozzle to include the following plastics:- Polyamides (PA4.6, PA6.6 and HTN)- Thermoplastic polyesters (PBT and PET)- Liquid crystalline polymers (LCP)- Polyether ether ketones (PEEK)

Needle guide LAZMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without subsequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring. Needle guide type LAZ has a tapered shape with a smaller contact surface which creates a smaller impression. This version is suitable for items with a minimal wall thickness and part geometries not permitting a larger impression.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of
the mould inserts required- Minimal shear stress
Needle guide KAThis is used when a second marking on the part is not permissible.
When selecting the material to be used, the needle hardness of 64 ±2 HRC is to be taken into account!

NEEDLE GUIDE VERSIONS
Needle guide version Antechamber version LA
Needle guide version Antechamber version LA
with titanium ring
Valve gate nozzle type 5NHTNeedle guide versions LA, LA with titanium ring, LAZ and KA
Needle guide LAMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without sub-sequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of the mould
inserts required- Minimal shear stress
Needle guide LASpecial version with titanium ring
Thermal insulation of the needle guide using a titanium ring expands the area of use of the valve gate nozzle to include the following plastics:- Polyamides (PA4.6, PA6.6 and HTN)- Thermoplastic polyesters (PBT and PET)- Liquid crystalline polymers (LCP)- Polyether ether ketones (PEEK)

Needle guide LAZMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without subsequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring. Needle guide type LAZ has a tapered shape with a smaller contact surface which creates a smaller impression. This version is suitable for items with a minimal wall thickness and part geometries not permitting a larger impression.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of
the mould inserts required- Minimal shear stress
Needle guide KAThis is used when a second marking on the part is not permissible.
When selecting the material to be used, the needle hardness of 64 ±2 HRC is to be taken into account!

Needle guide LAZMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without subsequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring. Needle guide type LAZ has a tapered shape with a smaller contact surface which creates a smaller impression. This version is suitable for items with a minimal wall thickness and part geometries not permitting a larger impression.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of
the mould inserts required- Minimal shear stress
Needle guide KAThis is used when a second marking on the part is not permissible.
When selecting the material to be used, the needle hardness of 64 ±2 HRC is to be taken into account!

Needle guide version Antechamber version LA
with titanium ring
Valve gate nozzle type 6NMTNeedle guide versions LA, LA with titanium ring, LAZ and KA
Needle guide LAMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without sub-sequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of
the mould inserts required- Minimal shear stress
Needle guide LASpecial version with titanium ring
Thermal insulation of the needle guide using a titanium ring expands the area of use of the valve gate nozzle to include the following plastics:- Polyamides (PA4.6, PA6.6 and HTN)- Thermoplastic polyesters (PBT and PET)- Liquid crystalline polymers (LCP)- Polyether ether ketones (PEEK)

If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without subsequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring. Needle guide type LAZ has a tapered shape with a smaller contact surface which creates a smaller impression. This version is suitable for items with a minimal wall thickness and part geometries not permitting a larger impression.

Needle guide LAZMade of powder-metallurgical steel
If necessary, the needle guide can be changed without great effort. By replacing the needle guide and needle, the gate point diameter can be made larger or smaller without subsequent reworking of the mould cavity. Thanks to a precise needle guide, the clean gate point can be closed with nearly no wear or burring. Needle guide type LAZ has a tapered shape with a smaller contact surface which creates a smaller impression. This version is suitable for items with a minimal wall thickness and part geometries not permitting a larger impression.
Advantages:- Long service life and wear-resistance- Wear parts are easy to replace- Outstanding and flash-free gate point quality- Very good visual surface quality- No replacement or subsequent reworking of
the mould inserts required- Minimal shear stress
Needle guide KAThis is used when a second marking on the part is not permissible.
When selecting the material to be used, the needle hardness of 64 ±2 HRC is to be taken into account!
